概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
Depositing DLC film on metallic substrates is often hindered by its poor adhesion caused by different thermal expansion coefficients of both steel and DLC film which drives total delamination. In order to solve this problem, various types of interlayers (Si, Mo, W, CrN, and TiN) have been tested.
実験 / Experimental
The samples were cut and polished until a mirror like surface is obtained in the cross section. All samples were analyzed and observed by Raman spectroscopy, scanning electron microscope (SEM), and energy dispersive spectroscopy (EDS).
結果と考察 / Results and Discussion
The thickness of DLC coating is 2.4 μm and a SiCx:H interlayer has a thickness of 0.5 μm. The bare nitrided AISI420J2 substrate is also shown. The nitrided layer thickness is 30 μm with different morphologies than the original substrate material.
